We’ve only had this couch for a few days. It does seem stiff, but haven’t been uncomfortable sitting on  it for extended periods of time. It will easily fit through narrow doors because it does require a little assembly, but nothing drastic or difficult at all. Fit and finish are very good, just note the back of the couch is low. It’s not a con just the way it’s designed.  Will have to see how it goes over time, but very satisfied with purchase, shipping and buying experience.
